hello can any one tell me is it easy to change the front fork seals on my beta rev3 & what oil do i use. (beta rev 3 year 2000) thanks

theres a topic somewhere on fork seals on my beta but that was a 02 and i think yours has got upside down forks so is probably different.

I found the fork seal replacement manual on Ryan Young's site very helpful. The Beta's fork internals are slightly different to the Sherco forks shown in the manual so play the disassembly and reassembly by ear but it's pretty straightforward and the actual seal replacement process is identical. If your bike has USD-ers then I'd assume that the process is the same, just... upside down(?)
